Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 5. The genus being monotypic, its species diagnosis is that of the genus. A genus of the auchenipterid subfamily Auchenipterinae that is distinguished from all other auchenipterid genera by the following combination of derived features: pectoral- and dorsal-fin spines with four rows of serrations running from base to the tip of the spines; (2) lateral margins of skull roofing bones ornamented with a single row of spines; (3) groove along dorsal midline posterior to dorsal fin, in which the adducted dorsal fin rests. Also the new genus has a unique combination of fin-ray meristics that are summarized as follows: D- II,4-5; P- I,5-6; V- i,5 (i,4 on opposite side); A- iv,16; C- i,7,9,i (Ref. 87761).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00341 - 0.01611), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
